running 4.4 libstdc++ testsuite using 4.5's libstdc++ shared library

Hi,

Better: between a genuine runtime binary compatibility issue and nothing, because an old testsuite will never be completely suited for a more recent system. Anyway, no idea: my impression is that the noise (ie, false positives) with this type of testing is overwhelming, like seeing a low mass Higgs at Fermilab ;)

Ps: the condition_variable PR likely is also a bit pointless, we are not guaranteeing full runtime binary compatibility for all the c++0x exp features, sorry.
